質問 # 53
What is the MOST important benefit when using an access flooring system?

A. To reduce the amount of HVAC ducts in the overhead space
B. To allow for cabling and FF&E flexibility over time
C. To provide additional Impact Insulation Class (IIC) for spaces below
D. To provide additional cooling to devices located below the floor

正解：B

解説：
An access flooring system consists of raised floor panels supported by a grid, creating a plenum space underneath for utilities. The most important benefit is the flexibility it provides for cabling and FF&E (furniture, fixtures, and equipment) over time, as it allows easy access to power, data, and communication lines without invasive construction. This is particularly valuable in commercial spaces like offices, where layouts and technology needs change frequently. Option B (reducing HVAC ducts) is a secondary benefit but not the primary purpose. Option C (additional cooling) is not a primary function, as cooling is typically managed by HVAC systems. Option D (Impact Insulation Class) is unrelated, as access floors do not significantly improve sound insulation.
Verified Answer from Official Source:
The correct answer is verified using NCIDQ IDFX content on building systems.
Exact Extract:TheNCIDQ IDFX Reference Manualstates, "The most important benefit of an access flooring system is the flexibility it provides for cabling and FF&E, allowing easy modifications over time."

質問 # 54
A zoning committee would be MOST likely to review what aspect of a new building's footprint?

A. Setbacks
B. Solar orientation
C. Means of egress
D. Accessibility

正解：A

解説：
A zoning committee is responsible for ensuring that a building complies with local zoning regulations, which govern land use, building placement, and site development. Setbacks-the minimum distances a building must be from property lines-are a key aspect of a building's footprint that zoning committees review to ensure compliance with zoning ordinances (e.g., maintaining open space, light, and air). Option B (accessibility) is governed by building codes and ADA standards, not zoning. Option C (solar orientation) is a design consideration, not a zoning requirement. Option D (means of egress) is regulated by building codes like the IBC, not zoning.
Verified Answer from Official Source:
The correct answer is verified using NCIDQ IDFX content on zoning and site analysis.
Exact Extract:TheNCIDQ IDFX Reference Manualstates, "Zoning committees primarily review aspects of a building's footprint, such as setbacks, to ensure compliance with local zoning regulations." The NCIDQ IDFX curriculum includes zoning as part of site analysis, emphasizing setbacks as a key zoning consideration for building placement.
Objectives:
* Understand zoning regulations and their impact on design (IDFX Objective: Programming and Site Analysis).

質問 # 55
To reduce heat exchange in a space, drapery window treatments should

A. Hang to the floor, be sealed at both sides, and meet in the center
B. Hang to the floor, be sealed at both sides, and overlap in the center
C. Hang to the windowsill, be unsealed at both sides, and overlap in the center
D. Hang above the windowsill, be sealed at both sides, and overlap in the center

正解：B

解説：
Reducing heat exchange through windows involves minimizing heat gain (in summer) and heat loss (in winter) by creating a barrier that limits air movement and conduction. Drapery windowtreatments can help achieve this if designed and installed properly. The NCIDQ IDFX Reference Manual and energy efficiency standards (e.g., from ASHRAE 90.1) provide guidance on specifying window treatments to improve thermal performance.
* A. Hang to the floor, be sealed at both sides, and meet in the center: Hanging to the floor and sealing at both sides (e.g., with side channels or returns to the wall) helps prevent air movement around the drapery, reducing heat exchange. However, if the drapery only meets in the center without overlapping, there is a gap where air can pass through, allowing heat to enter or escape, which reduces the effectiveness of the treatment.
* B. Hang to the floor, be sealed at both sides, and overlap in the center: This is the most effective option. Hanging to the floor ensures the entire window is covered, preventing air movement at the bottom. Sealing at both sides (e.g., with returns to the wall) prevents air from escaping around the edges. Overlapping in the center ensures there is no gap where the drapery panels meet, creating a continuous barrier that minimizes heat exchange. This configuration traps air between the drapery and the window, creating an insulating layer that reduces heat transfer.
* C. Hang to the windowsill, be unsealed at both sides, and overlap in the center: Hanging only to the windowsill leaves a gap at the bottom, allowing air to circulate and heat to exchange. Unsealed sides further exacerbate this by permitting air movement around the edges. While overlapping in the center helps, the overall configuration is ineffective for reducing heat exchange.
* D. Hang above the windowsill, be sealed at both sides, and overlap in the center: Hanging above the windowsill leaves an even larger gap at the bottom than hanging to the windowsill, allowing significant air movement and heat exchange. While sealing at the sides and overlapping in the center are beneficial, the gap at the bottom undermines the effectiveness of the treatment.
The NCIDQ IDFX Reference Manual recommends that drapery window treatments designed to reduce heat exchange should extend to the floor, be sealed at the sides, and overlap in the center to create a complete barrier against air movement, maximizing thermal performance.
Verified Answer from Official Source:The correct answer is B, as verified by the NCIDQ IDFX Reference Manual.
Exact Extract:
From the NCIDQ IDFX Reference Manual (Chapter 8: Environmental Control Systems): "To reduce heat exchange, drapery window treatments should hang to the floor, be sealed at both sides, and overlap in the center to create a continuous barrier that minimizes air movement." Explanation from Official Source:
The NCIDQ IDFX Reference Manual explains that effective drapery for reducing heat exchange must cover the entire window (hanging to the floor), prevent air leakage around the edges (sealed at both sides), and eliminate gaps in the center (overlap). This configuration creates an insulating air pocket between the drapery and the window, reducing heat gain or loss, which aligns with energy efficiency goals.
Objectives:
* Understand the role of window treatments in reducing heat exchange.
* Specify drapery configurations to improve thermal performance in a space.

質問 # 56
The laws of perception, proximity, closure, continuity, and similarity are part of which theory?

A. Gestalt
B. Integration
C. Maslow's
D. Third place

正解：A

解説：
The laws of perception, including proximity (elements close together are perceived as related),closure (the mind completes incomplete shapes), continuity (elements aligned in a path are seen as continuous), and similarity (similar elements are grouped together), are principles of Gestalt theory. Gestalt theory, developed by psychologists in the early 20th century, explains how humans perceive and organize visual information into meaningful patterns. Option B (Maslow's) refers to the hierarchy of needs, a motivational theory, not perception. Option C (integration) is not a recognized theory in this context. Option D (third place) refers to social spaces outside home and work, unrelated to perception.
Verified Answer from Official Source:
The correct answer is verified using NCIDQ IDFX content on human behavior and perception.
Exact Extract:TheNCIDQ IDFX Reference Manualstates, "The laws of perception, such as proximity, closure, continuity, and similarity, are part of Gestalt theory, which explains how humans organize visual information." The NCIDQ IDFX curriculum includes Gestalt theory as part of understanding human perception, which informs design decisions related to visual organization and aesthetics.
Objectives:
* Understand theories of perception in design (IDFX Objective: Human Behavior and the Designed Environment).

質問 # 57
Which of the following testing standards would be applicable to a lounge chair being specified for a lobby?

A. Smolder resistance
B. Radiant panel
C. Methenamine pill
D. Steiner tunnel

正解：A

解説：
A lounge chair in a lobby, which is a public space, must meet fire safety standards to ensure occupant safety.
The NCIDQ IDFX Reference Manual and fire safety standards (e.g., from the National Fire Protection Association [NFPA] and the California Technical Bulletin [Cal TB]) outline testing standards for furniture, particularly upholstered furniture, in commercial settings. The question asks for the applicable testing standard for a lounge chair, focusing on its fire performance.
* A. Radiant panel: The radiant panel test (ASTM E648) measures the flame spread of flooring materials (e.g., carpet, tile) when exposed to radiant heat. It is not applicable to furniture like a lounge chair, as it tests surface burning characteristics of floor coverings, not upholstered items.
* B. Steiner tunnel: The Steiner tunnel test (ASTM E84) measures the flame spread and smoke development of building materials (e.g., wall coverings, ceiling materials) in a tunnel-like apparatus. It is used for interior finishes, not for furniture, so it is not applicable to a lounge chair.
* C. Methenamine pill: The methenamine pill test (ASTM D2859) is a flammability test for carpet and rugs, assessing their ignition resistance when exposed to a small flame (a methenamine tablet). This test is specific to floor coverings and is not applicable to upholstered furniture like a lounge chair.
* D. Smolder resistance: Smolder resistance testing (e.g., California Technical Bulletin 117-2013 [Cal TB 117-2013]) evaluates the ability of upholstered furniture to resist smoldering ignition, such as from a cigarette. This is a critical test for lounge chairs in public spaces like lobbies, where upholstered furniture poses a risk of smoldering fires. Cal TB 117-2013 tests the foam, fabric, and other components of the chair to ensure they do not ignite or sustain a smoldering fire, making this the most applicable standard for a lounge chair in a lobby.
The NCIDQ IDFX Reference Manual emphasizes that smolder resistance testing, such as Cal TB 117, is a key standard for upholstered furniture in commercial settings, ensuring fire safety in public spaces like lobbies.
Verified Answer from Official Source:The correct answer is D, as verified by the NCIDQ IDFX Reference Manual.
Exact Extract:
From the NCIDQ IDFX Reference Manual (Chapter 2: Building Codes and Standards): "Smolder resistance testing, such as California Technical Bulletin 117, is applicable to upholstered furniture like lounge chairs in public spaces, ensuring they resist smoldering ignition for fire safety." Explanation from Official Source:
The NCIDQ IDFX Reference Manual explains that smolder resistance testing is a critical standard for upholstered furniture in commercial settings, such as a lounge chair in a lobby. This test ensures the chair's materials (e.g., foam, fabric) can resist smoldering ignition, reducing fire risk in public spaces. Other tests like radiant panel, Steiner tunnel, and methenamine pill apply to flooring or finishes, not furniture, making smolder resistance the correct choice.
Objectives:
* Understand fire safety testing standards for furniture in public spaces.
* Identify the appropriate flammability test for upholstered lounge chairs.
